FAILURE ANALYSIS SUPPORTING DEVICE, INCIDENT MANAGING SYSTEM, FAILURE ANALYSIS SUPPORTING METHOD, AND PROGRAM

摘要

To provide a failure analysis supporting device which quickly presents an appropriate failure solution plan when a failure has occurred in a system.SOLUTION: The failure analysis supporting device includes an extraction unit, a generation unit, a calculation unit, and an output unit. The extraction unit specifies a format for each of error logs obtained from a monitoring object device, and extracts each of the specified format as a log pattern. The generation unit determines a log pattern to which each of the error logs contained in one day corresponds, and generates a log pattern list comprising the log patterns. The calculation unit calculates similarity between an error log at the occurrence of the failure and error logs in an incident occurring day on the basis of the error log at the occurrence of the failure and the log pattern list on the incident occurring day. The output unit outputs a failure solution of the incident estimated from the error log at the occurrence of the failure on the basis of the similarity.SELECTED DRAWING: Figure 1
